    Internet is ridiculously slow in the EVENING ONLY

    Hi guys, I'm new here, but I've been reading alot of post from here. I will try to post as much info that I can, to better assist anyone that can help me.

    I live in Georgia, and am using Charter Cable for my ISP. My rated speed is 5MBs down and 500KBs ups. In the morning, everything is on par, when using this following speedtest (http://speedtest.optilink.us/). It gets as close as it can, 4.85Mbs, and 500KBs, and 99% quality of service which is very good. It's the same every morning, almost like clock work up until around 3:00 or 4:00 PM. Late in the day, when I do the speed test, it bounces around like crazy. Sometimes, it's 2 or 3Mbs, and sometimes, it's less than 1Mbs, and the quality of services drops below 50 percent for the rest of the day. Only the upload speeds stays consistent at 495Kbs to 500Kbs through all this. .

    Here is my Tracert for tonight:

    I realize that cable, everyone is sharing, so the more that gets on, the less bandwidth one has to surf with, and maybe that is all it is.

    Hope that helps...

    Thanks

    What electrical equipment in your house is usually turned on at the time that your speed bounces around? Like air-con unit or something similar.

    Is your modem placed near to some other electrical device?

    Just under my desk, and the computer is about 3 feet from it. Nothing out of the ordinary is around it other than my desk.

    Clean your comp with CCleaner.

    Scan your comp with

    AVG antispyware
    SpyBot

    Trust me, my pc should be free of most anything. I check it often, with most of apps you mentioned, plus a few others.

    Hijackthis, MS Defender, TrojanHunter, AVG Virus, AVGRootKit.

    I usually only have around 30 processes running at a giving time. I keep my PC tiddy.

    The NDT reported packet losses and signal stalling:

    The connection stalled 1 times due to packet loss
    The connection was idle 0.45 seconds (4.5%) of the time
    C2S throughput test: Packet queuing detected: 1.02%

    This connection is network limited 99.83% of the time.
    Excessive packet loss is impacting your performance, check the auto-negotiate function on your local PC and network switch
    The cause may be malware or electrical interference on the signals.

    Not sure if that fixed it or if it's because it's morning time over here, but everythings back up to par, after making them chagnes and rebooting. Will no for sure later this evening.

    Thanks for you help

    A clear signal at our end would give 3 equal ping times at the modem in hop 2.

    Make sure you do not coil up any excess length of signal or power cables. What room is on the other side of the wall where your modem is located?

    Have you called Charter yet? That would be the first thing I would do since if its not steady and constantly a problem then its most likely not your problem.

    Just throwing this out there, if the speeds are so slow only during evening, wouldn't that have something to do with perhaps node saturation?

    If there is node saturation, the tracert would show a start of spike in the 3 ping times at hop 3, 4 or 5 - usually above 100ms. In some posts, the spike can be above 300ms.
